Auto Light Energy Saver Kit v4
Build an Automatic Energy-Saving Light with Gas Leak Telegram Alerts – Pico W Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Create a compact automatic light controller that cuts wasted electricity by turning lights on only when someone is present. Add a safety layer with a gas sensor that sends instant Telegram alerts to your phone while you’re away — all powered by the tiny Raspberry Pi Pico W.
What You'll Build
You'll assemble a complete smart energy-saving system inside the included ABS enclosure. When the PIR sensor detects motion, the light switches on; when the room is empty, it turns off. Meanwhile, the MQ-2 gas sensor continuously monitors for leaks. If a dangerous level is detected, the active buzzer sounds a local alarm and the Pico W instantly pushes a Telegram message to your mobile — so you’re always aware, even when you’re not at home.
What You'll Learn
- Connect PIR and gas sensors to a Raspberry Pi Pico W and read their output signals
- Write MicroPython code to control outputs and implement energy-saving logic
- Configure a Telegram bot and send real-time notifications from your device
- Design a compact, low-power IoT device for real-world home automation

Who This Kit Is For
This kit is designed for young makers in India, from Class 5 students exploring ATL Tinkering Lab projects to Class 12 students preparing CBSE science exhibitions. It’s perfect for school STEM clubs, first-time IoT hobbyists, and anyone seeking a safe, guided introduction to Raspberry Pi Pico W and home automation.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to launch the AI companion, which gives step-by-step help; you can also reach us on WhatsApp for direct support.
Does this kit require soldering?
No, all connections use jumper wires and breadboard-friendly components — no soldering needed.
Can I run it on a battery?
Yes, the Pico W can be powered from any USB power bank. The code is written to keep power consumption low for energy-saving operation.
How hard is it to set up Telegram notifications?
The AI companion walks you through creating a bot in about 10 minutes, and the provided code handles the rest.
Energy Saving — Pico W reads PIR and gas sensor. Sends Telegram notification if alarm triggers while away from home.
